| abstract |
A recombinant delivery microorganism that displays on its surface a binding moiety that competes with a ligand for binding to a receptor for the ligand, when administered to an animal. The binding moiety comprises an oligosaccharide, which comprises a sugar residue that is attached to an acceptor moiety by a glycotransferase that is encoded by an exogenous nucleic acid which is present in the microorganism. |
